How this service works
Call when an agent needs SRV records at _sip._udp.{hostname} for SIP over UDP. The caller sends the registrable domain, not the underscored name. Exact $0.004 USDC. Prefer unpaid POST /v1/sandbox/dns-srv-sip-udp first.
Output
Returns SRV DNS record data for _sip._udp.{hostname}, including one or more records each containing priority, weight, port, and target hostname values used for SIP-over-UDP service routing.
Example use cases
VoIP SIP server discovery
“I need to find the SIP over UDP server endpoints for voipprovider.com — can you pull the SRV DNS records so I know what host and port to connect to?”
SIP routing configuration check
“What are the _sip._udp SRV records for mycompany.com? I'm setting up a SIP trunk and need the priority, weight, and port from DNS.”
Telecom onboarding validation
“Before I onboard a new SIP carrier, can you resolve the SRV records for SIP UDP at carrierdomain.net so I can verify they have DNS configured correctly?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/dns-srv-sip-udp?utm_source=zero.xyzWhen to prefer
Use this endpoint when an agent needs to discover SIP-over-UDP service endpoints for a domain via DNS SRV records, specifically the _sip._udp prefix. Prefer the free sandbox endpoint (/v1/sandbox/dns-srv-sip-udp) for testing. Choose this over general DNS lookup tools when you specifically need SRV record data scoped to the SIP UDP service type.
Side effects
- Hostname not found in DNS — returns empty or NXDOMAIN result
- Malformed hostname input exceeding 253 characters
- Domain has no _sip._udp SRV records configured
- DNS resolution timeout or upstream failure
- Invalid domain format rejected by input validation
